BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 739,881, dated September 29, 1903. Application filed M1164, 19oz. Seria1 No.1l0,213. (Nomoclel) To aZZ whom it may concern.-

Beitknown that LOHAUNOEY W. KILBORN, a resident of Rosenhayn, in the countyof Oumberland'and State of New Jersey, have 5 invented certain new and useful Improvements in Brick-Machines; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which i it appertains to make and use the same.

20 grade brick and is produced at a great saving in expense.

With this object in view the invention con-' sists in certain novel features of construction and combinations and arrangements of parts, 2 as will be more fully hereinafter described,

and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation, partly in section, illustrating my improvements. Fig. 2 is a 0 view in cross-section. Fig. 3 is a front view,

and Fig. 4 is a plan view partly in horizontal section. 7

1 represents the ordinary conical com pressing feed-spout, provided with a worm or screw 5 2 to force the brickmaterial through the angular die 4 at the end of the spout in the form of a bar 3 of brick material. On die 4 at the end of spout 1 a frame 4 of any suitable material is secured in any approved manner and 0 is provided at its outer end with a die 5*, which may be of the same size or even smaller than die 4. This frame 4? supports two cylinders 5, and the frame is made with a duct 6, connecting the cylinders with the bar-pas- 5 sage in said frame at its top and gradually widens and curves toward the die 5, so as to insure the material from the cylinders 5 being carried on and pressed into the surface of brick-bar 3. This duct 6 also communicates with similarly-shaped ducts '7 at the sides of the frame to direct the coating material against the sides of brick-bar 3, and as the brick-bar is cut vertically the top and sides of the bar form one side face and the ends of the bricks, and it will be seen that the exposed faces of the latter when laid in a wall will be coated with superior material.

In cylinders 5 angers or worms 8 are located and turned by long shafts 9, projecting up out of the cylinders, and scrapers 10 are secured on these shafts in the cylinders to remove the brick material from the sides of the cylinders and compel its downward passage and be taken up by the angers or Worms and forced in a constant stream against the brickbar. On the upper ends of shafts 9 gears 11 are secured and mesh with a gear 12 on a vertical drive-shaft 13, which latter receives motion through the medium of intermeshing gears 14 15, connected up with any source of power.

The operation of my improvements is as follows; The brick material is forced from spout 1 by the worm 2 in the form of a bar, and as the latter passes cylinder 5 the finishing material therein is forced against the top and sides of the bar through ducts 6 and 7 by means of angers or worms 8 to tightly press said finishing material against the bar'and compel it to adhere thereto and become a permanent part of the brick, forming a side face and ends of the bricks when out.

It will thus be seen that with my improvements I am enabled to use a low grade of brick material for the body of the brick and coat the same on all exposed faces with highgrade material colored in any desired man- 7 ner, thus resulting in a brick which has all the good features of a high-grade brick and the additional good feature of a great saving in expenseof manufacture.

A great many slight changes might be made in the general form and arrangement of the several parts described without departing from my invention, and hence I do not wish to limit myself to the precise construction set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, isr 1. In a brick-machine the combination with a feed-spout and two dies spaced apart and communicating with said spout, of a separate frame disposed between said dies and having a downwardly and forwardly projecting duct in its upper portion, a cylinder supported on said separate frame and communicating with said duct, a shaft mounted in said cylinder, an anger or worm on the lower portion of said shaft and a scraper secured to said shaft above the anger or worm.

2. In a brick-machine,the combination with a feed-spout and two dies spaced apart and communicating with said spout, of a separate frame disposed between said dies, said frame having a downwardly and forwardly projecting duct in its upper portion, and also having downwardly and forwardly projecting ducts in its side portions, two cylinders supported upon said separate frame and communicating with said ducts, a shaft mounted in each cylinder, a worm on the lower portion of each shaft, a scraper secured to each shaft above the worm, a gear-wheel on each shaft, a third shaft mounted on said frame, a gear-wheel on the third shaft meshing with the first-mentioned gear-wheels and means for transmitting motion to said third shaft.

3. In a brick-machine,the combination with a feed-spout and two dies spaced apart and communicating with the feed-sp0nt,of a frame located between said dies, said frame having a duct extending from its top downwardly and forwardly, the outlet-mouth of said duct formed by the two dies, said frame also having lateral ducts communicating with the first-mentioned duct, the outlet-mouths of said lateral ducts also formed by said dies, 2. cylinder located upon said frame, and means in said cylinder for forcing'material through the ducts in the frame and onto the bar of clay passing through thedies.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
